Thisinvention relates to coin controlled vending apparatus, and has forone` of its objects to provide a device of'thisgcharacter whereby aplurality of coins of varying size. or value maybe ,5 utilized in thesameV apparatus to actuate the delivery mechanism. Y Y Another object-ofthe invention is-toprovide an apparatusof this class inwhichtwo coins ofdiierent sizes are required to'actuate the deliv-v ery mechanism, and inwhich means are provided for quickly transforming the apparatus into aone-coin apparatus.

With these .and other objects in view, the invention consistssubstantially inthe structure herein described and claimed, andasillustrated in the accompanying drawingsin which:

The improved device is Venclosed ina casing or shell including spacedsides 10 and 1l, bottom ,12, andtopl. The sides l() and l1 are connectedat one Yside by an end member 14 hingedly connected thereto as shown atl5 to provide for access to the interior of the casing. At the oppositesides the members 10 and li extendifor a vertical section on the line4--4 of distance in parallel relation and this portion is.

connected .by anend member 16, while the remai-ning portions o1 thesides areconnected by an outwardly curving portion 17, the terminal .1 8of the latter being spaced from vthe bottom 12. li-i-zxtending betweenthe sides lo and Vll'ris a transverse horizontal partiticnor diaphragml)and a curved portion 20, the portion 2) being'spaced from the curved endmember 17 and extending to the bottom 12, thus forming a curved chamber21 opening at the upper end into the interior of the casing andending-at the lower, end opposite the opening beneath the terminal 18 ofthe member 17 and forming aireceptacle for the ejected articles.

LocatedV in the space above the partition 19 is a holder 22 for thearticles to be ejected, and formed to vcorrespond to the shape ofthearticle, for illustration a `supply'of cigarettes or the like, andindicated at 23. The holder 22'opens at the upper open end through-thetop 13 of the casing,

and terminates at its lower open end a distance diameter, of thecigarette or other article 23, as

shown in'Fig 2. 'The partition 19 is formed with a slot 24, and slidableon-the partition is an'ejector plate 25, of suitable form for itspurpose, having a stud 2 6 extending below the lower face of the plate.A spring 28 is coupled to hold the plateyieldably in withdrawn position,with the face 27 in verticalalignment with the adjacent wall of theholder 22, as shown in Figs.,2 and 3. The face 27 is less in vheightthan the diameter of the articles to be ejected, so that whenthe plate25 is actuated against the resistance of the spring 28, the f ace 27will eject the lowermost of the articles. 23 (for instance a cigarette)`and pass beneath the next one above but without affecting cigarettes inthe holder will force the lower one tovsettle on the partition 19 inposition to be ejected at the next operation of the plate 25. Thus thearticles will be ejected one at a ltime by each action of the plate 25.

Mounted `for rotation through the casing is a shaft 29, and supported onthe shaft within the casingis a drum 3() having a plurality of spacedlugs 31'pro'jecting from its periphery into the path of the stud 26.V Bythis arrangement, when the drum 30 is rotated, they lugs 31 willconsecutively engage the stud 26 and actuate thel plate 25 a suicientdistanceto eject a single cigarette, and

then pass from the inuence of the lug when the r reaction of the spring28 will return the ejector plate to its former position as beforedescribed.

Means are provided for rotating the druma predeternlined distance only,consisting of an. operating handle v32 secured to the'shaft `29er--ternally of the side 10 of the casing, a stop 33 on the side 10 to limitthe throw of the handle, a counterweight 34 on the shaft 29 operative toreturn the shaft to its former position, and a spring attached to theinner face of the side 10 and curved to engage intermittently in sockets36, one socket for each. of the lugsr31 to stop the drum at a positionof engagement with the stud of the ejector. Each forward movement of thehandle 32 will cause the ejection of one'of the articles, and when theoperator releases the handle the spring 28 will return the ejector plateand the counterweight 34 will return the handle to operativeposition asbefore stated.

Coin controlled means are provided for locking K the drum 30 stationaryand to be released only by the insertionv of a coin.V The interior ofthe. drum 30 is provided with aplurality of segments 37 corresponding innumber with spaces between the lugs 31, and with spaces 38 between thesegments. Extending inwardly from the sideof the drum'are'pins 39, oneadjacent to each of the Y segmentsv 37 and these pins 39 areoffset `fromthe recesses 38 and' act to stop the drum on its return movement withthe arm 57 directly in register with the respective recess v'38. Mountedpivotallyto swing on the member D and in the mounting E is a trip member40 having a coin receiving recess 41, the counterweight 34 operating tohold the( trip 40 normally in elevated position with therecess 41 in aposition to receive the coinA from a coin duct 42, to be explained.` Acoin duct 42 `is supported within the casing opening at itsupper endthroughthe top 13 and opens at its lower end above the recess 41 of thevtrip 40. A coin inserted in the duct 42 will pass into the recess 41and by its weight will trip the memberY 40 on its pivot 43. Pivoted alsoat 43 lupon the trip member 40 is a yokedevice 44operative to: hold thecoin,-indicated at 45,`within the recess 41 until the shaft 29 isrotated by the handle 32. The

Yweight of the coin is sufficient to overbalance the A member 40 andwhen the handle Y22 is actuated to move the ejector plate, the trip 40carrying the coin 45 will be advanced and carry the yoke 44 with it.Attached'at a suitable point on the casing 10 is a stop 46 which theyoke 44 engages when the trip member is advanced and thus secures thefree end of the yoke against further movement, permitting the trip tocontinue and release A,the coin which falls into a suitable receptacle(not shown). When the handle 22 Vis released, the ccunterweight 34returns the handle and the trip device V40 and its attached yoke 44 toformer position to receive the next coin. Y

Extendingl from the body of the trip member 40 is an arm 48 terminatingnear the wall of the drum 30, and extending inwardly toward the innerface oi the drum wall there to engage an annular member 49 secured tothe drum. Associated with the annular member for engagement purposes arepins 50, one for each of the studs 3,1, and when the trip 40 isdepressed by the coin, the arm 48 will be moved to successively engagethe pins 50 and lock thev trip member in engagement with the drum 30, toactuafte that member uponthe movement of the handle.

The duct 42 is just large enough to receive a Vpredetermined size ofcoin, for example, a dime.

duct 42, and is vdesigned toreceive a ve Acent VorY nickel piece.Pivoted at 52 in a standard 53 is,r

another trip device 54 having an outwardly open-r 'Y l ing recess 55 inone end and normally disposedY in a poised position beneath the outletend Yof the Y duct 51, or in position to receive a coin therefrom,

the latter indicated at 56 in Fig. 4. Extending from the body .of thetrip member 54 is yan amr 57, projecting when in one positionconsecutively into the recesses 38 between the segments 37, and

held thereby kin.` locked position when the recessed end of the tripmember 54 elevated, as

shown in Fig. 4.' By this means, so long as there` iszno coin 56 in theslot 51, the trip member 54' will be heldin poised position and the drumheld from rotation. .When however a coin is deposited in the duct 51,its Weight will overcome thetrip member, elevate the arm 57 from therecess 38,

to the position shown in Fig. 11, and permit the drum to be rotated andthe cigarette ejected as before described.

A coinereceptacle 58 is located the casing in position to restrain thecoin from leaving the recess 55 untilthe trip has been depressed therebyand, to then receive the coin from the trip 54, and a receiving drawer59 is preferably located beneath the receptacle 58, as representedinvFig. 12. v Y

By this arrangement the nickel trip locks the device from action until adime is deposited, and

the dime trip is held inV inoperative position until a nickel coin isdeposited. Hence the two-coin` apparatus requires thatboth coins bedeposited to enable the delivery mechanism to be actuated.

'I'o transform the apparatus into a dime actu- 7 ated device, itis onlyVnecessary to remove the fulcrum pin 52 and the trip 'lever 54-57 Havingnow described my invention, that whichV I claim to be new and desireto'secure'by' Letters V- Patent is:
